3.3 Fuses
The instrument panel has three fuse boxes mounted. To have access to the fuses, unscrew the
screw and open the instrument panel cover.
Sixteen fuses (see Figure above) protect the following tractor electrical circuits against
overloads:
1 — Braking signal (15 A);
2 — Cab lamp, roadtrain rear operating headlights (15 A);
3 — emergency stop signaling (15 A);
4 — Windshield and rear window wipers and window washer (25 A);
5 — Horn (15 A);
6 — Headlight upper beam (25 A);
7 — Front operating headlights (25 A);
8 — Heater fan, rear PTO control system and turning on the rear axle differential lock (25
A);
9 — Power supply to consumers working with the starter and instrument switch in the
“instruments ON” position (25 A);
10 — Air conditioner control (for BELARUS-1025.3 tractors if an air conditioner is
installed on request instead of the heater) (25 A);
11 — Left clearance lamps (7.5 A);
12 — Right clearance lamps and instrument panel illumination (15 A);
13 — Right headlight lower beam (7.5 A);
14 — Left headlight lower beam (7.5 A);
15 — Instruments and speed sensors power supply (7.5 A);
16 — Turn indicators relay switch (for tractors BELARUS-1025.3 — also power supply of
the SP unit and the SP relay switch winding) (15 A).
A battery voltage charge circuit fuse with 60 A rating is located on a bracket mounted on
the body of the HLL oil tank
The fuse (1) (see Figure below) with 20 A rating for charging of an extra battery, which is
only used to start the engine 24 V, is integrated into the body of the voltage changer (2).
1 — fuse, 2 — voltage changer.
Warning!
To avoid burnout of the tractor wiring, never use fuses of a higher current rating
that indicated above. If the fuse blows frequently, find the cause and fix the problem.
